Today we released the first Alpha version for Authoritative Server version 4.6.0.
Version 4.6.0 mostly brings small improvements and fixes, but there are two notable new features:
- support for incoming PROXY headers
- support for EDNS cookies
Support for PROXY headers allows you to put a load balancer (such as dnsdist) in front of the Authoritative Server, while still having the Auth see the actual IPs of clients talking to it.
EDNS Cookies allow resolvers that support it to have an extra layer of authentication on their communication with the Authoritative Server.
A full list of changes can be found in the changelog.
